Jiangyin Centersky Electrical Appliance Co., Ltd

Transformer EI laminations for many types of tansformer and reactors. Jiangyin Centersky produces 15 000 Tons of standard and customized E&I laminations for many types of voltage transformer industries and the balast and reactors. Single phase EI lamination are for autotransformer, voltage transformer and etc. Larger three phase EI lamination are for reactors. Material processed include 0.35 to 0.5 mm thick. Fully Processed Silicon Steelsand Grain Oriented 0,17 to 0,35mm thick Silicon steel grades. Standard EI laminations permanently available through stocks in China, fast deliver to Asia, Europe, America, Middle East, etc. (source:https://www.ei-lamination.com/transformer-ei-lamination-2/)

Every year Jiangyin Centersky has a big demand for silicon steel raw material. For guarantiing the good quality of transformer EI Lamination, we cooperated with WISCO and BAOSTEEL, WISCO and BAOSTEEL combined into one group in 2016 , they are the largest steel group in China, also very famous in the world. Our company has below raw materials in stock for manufacturing silicon steel EI lamination : CRNGO: 0.5mm thickness: 50WW800, 50WW600, 50WW470, 50WW350. 50AW290, 50AW270 and etc. 0.35mm thickness: 35WW440, 35WW400, 35WW300 and 35WW270 etc. CRGO: 0.3mm thickness: 30P130, 30P120 and etc. 0.35mm thickness: 35Q155 and etc. 0.27mm thickness, 0.23mm thickness. Based on adequate quantity of raw material and high efficient production, we can manufacture many types of silicon steel EI lamination in different grade material, which can satisfy with the demand of the customers fully.

Three phase transformers are more economical for supplying large loads and large power distribution. Even though most of the utilization equipments are connected by the single phase transformers, these are not preferred for large power distribution in the aspect of economy. The three phase power is used in almost all fields of electrical power system such as power generation, transmission and distribution sectors, also all the industrial sectors are supplied or connected with three phase system. Therefore, to step-up (or increase) or step-down (or decrease) the voltages in the three phase systems, three phase transformers are used. As compared with the single phase transformer, there are numerous advantages with 3 phase transformer such as smaller and lighter to construct for the same power handling capacity, better operating characteristics, etc. In order to achieve the ideal working efficiency and high permeability of the transformer, cold-rolled non-oriented or orient

With the rapid expansion of “COVID-2019” epidemics worldwide, many of our customers have encountered certain difficulties in various aspects, such as EI lamination procurement and electrical transformer manufacturing. In order to better support our customers, we are optimizing as following. Increase the production capacity of regular lamination and standard EI core, maintain a certain inventory in order to improve corresponding delivery time. Adjusting and optimizing the tooling process to make them suitable for each requirements of different holes and apertures, especially single phase EI core and triple phase EI core, to speed up the order processing time. We will continue to conduct other feasibility studies and keep posted if there are other measures. (source:https://www.ei-lamination.com/supporting-clients-in-the-special-period/)
